SECOND FAO/OIE REGIONAL MEETING ON AVIAN INFLUENZA CONTROL IN ASIA
Ho Chi Minh City (Vietnam) 23-25 February 2005 5
RECOMMENDATION No. 4
Strategies for surveillance and control of avian influenza
Considering:
1. The importance and the regional and international dimensions of the AI crisis affecting animals and the
potential public health implications;
2. The necessity to stop the cycle of infection within identified reservoirs and prevent spill over into other
susceptible animal species and man;
3. The need to prevent the spread of AI virus to unaffected countries;
The meeting recommends that:
1. Countries plan control strategy based on scientifically designed risk analysis and surveillance surveys
that identify reservoir species, agro-ecological areas and farming systems likely to maintain the
infection;
2. The main risk infection pathways be mapped and appropriate and targeted surveillance strategies
defined;
3. Disease be controlled at source through implementation of risk reduction interventions, including
stamping-out, vaccination, improved biosecurity and education awareness. In AI free countries,
vaccination would not normally be considered for the purpose of prevention;
4. Vaccination in poultry if applied in an appropriate manner can be used as an additional tool to protect
human health and help towards the elimination of infection. However, vaccines should comply with OIE
standards and vaccination strategies should be consistent with guidelines developed by FAO and
supported by OIE;
5. That surveillance programmes be elaborated before vaccination is introduced. Likewise, an exit strategy
has to be identified;
6. That Regional and International bodies provide assistance to countries in the region in capacity building;
7. That, wherever appropriate, diagnostic tests capable of differentiating infected from vaccinated (DIVA)
birds be applied;
8. The efficacy of risk reduction and prevention procedures be monitored through targeted surveillance
activities, including:
• post vaccination surveillance to measure efficacy of vaccination, early identification of virus
circulation, monitoring of genetic drift and emergence of new strains
• monitoring reservoirs, including live bird markets
• monitoring disease status of compartments or zones.
